drm/amdgpu: Reduce SG bo memory usage for mGPUs

2021-12-13T21:33:16Z

For userptr bo, if adev is not in IOMMU isolation mode, RAM direct map to GPU, multiple GPUs use same system memory dma mapping address, they can share the original mem->bo in attachment to reduce dma address array memory usage.

drm/amdkfd: err_pin_bo path leaks kfd_bo_list

2021-12-01T21:16:00Z

Refactor userptr and pin_bo path to make it less confusing, move err_pin_bo label up to remove mem from process_info kfd_bo_list. Signed-off-by: Philip Yang Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: fix double free mem structure

2021-12-01T21:07:13Z

drm_gem_object_put calls release_notify callback to free the mem structure and unreserve_mem_limit, move it down after the last access of mem and make it conditional call. Signed-off-by: Philip Yang Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Fix double free of dmabuf

2021-11-22T19:59:08Z

amdgpu_amdkfd_gpuvm_free_memory_of_gpu drop dmabuf reference increased in amdgpu_gem_prime_export. amdgpu_bo_destroy drop dmabuf reference increased in amdgpu_gem_prime_import. So remove this extra dma_buf_put to avoid double free. Signed-off-by: xinhui pan Tested-by: Felix Kuehling Reviewed-by: Felix Kuehling Acked-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Pin MMIO/DOORBELL BO's in GTT domain

MMIO/DOORBELL BOs encode control data and should be pinned in GTT domain before enabling PCIe connected peer devices in accessing it Signed-off-by: Ramesh Errabolu Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Update BO memory accounting to rely on allocation flag

2021-11-22T19:45:01Z

Accounting system to track amount of available memory (system, TTM and VRAM of a device) relies on BO's domain. The change is to rely instead on allocation flag indicating BO type - VRAM, GTT, USERPTR, MMIO or DOORBELL Signed-off-by: Ramesh Errabolu Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Fix dangling kfd_bo pointer for shared BOs

2021-11-05T18:12:45Z

If a kfd_bo was shared (e.g. a dmabuf export), the original kfd_bo may be freed when the amdgpu_bo still lives on. Free the kfd_bo struct in the release_notify callback then the amdgpu_bo is freed.
